Stephen Hawking - Aliens

That's the next issue, in which fusion may be able to handle. If we can develop some sort of energy technology that has substainability and longevity to outlast many generations then of course we could manage to survive. I would imagine we would kill our own race off of this planet before anything were to happen to the sun, but if? Who knows.

And I would agree, Europa would essentially be the best place we could ever go to. But would it be possible within the next few hundred years? Could be. There needs to be an enormous breakthrough in prupolsion technology that could legitimately get humans to that planet in a managable amount of time (20-30 years?). 800,000,000 miles is the estimated average distance from the Earth to this unknown planet, and it does change with the orbit around Jupiter. There are so many obstacles including asteroids and other space debrit in the way of sending a satellite/ship that long of a distance. But I think in the next 50 years our technology should have evolved enough to make something like this feasible.

We need to atleast be gearing up to send unmanned ships and scientific gathering equipment to gauge more information of this other planet.
